Designing and modeling quick hitch weldments for wheel loader attachments using CAD, with a strong focus on manufacturability and alignment with design intent

A leading global manufacturer of wheel loaders partnered with ALTEN to address a critical engineering challenge : the design and modeling of quick hitch weldment for wheel loader attachments. The goal was to ensure manufacturability, and precise alignment with design intent using advanced CAD methodologies. The client was looking for more than just engineering support; they needed a strategic partner with deep technical expertise, a proactive mindset, and design agility to tackle the complexities of quick hitch weldment plate development. ALTEN stepped in with a structured, design-led, and cross-functional approach delivering not just cost savings, but faster execution cycles and stronger collaboration across engineering, procurement, and manufacturing teams.

Challenge:

  • Multi-functional geometry: Must accommodate various attachment types (buckets, forks, grapples), requires precise alignment with loader arms and pin locations, complex profiles to ensure secure locking and quick release.
  • Manufacturing constraints: Design must be optimized for cutting and welding, avoid tight tolerances and complex bends that increase fabrication cost, material selection impacts weldability and durability.
  • Design Intent alignment: Geometry must reflect operational load paths, Model weldment features to simulate real-world joints, Use CAD configurations to support multiple loader models and variants
  • Cross-functional collaboration: Integrate input from engineering, procurement, and manufacturing, ensure traceability of design changes, align with PLM systems for BOM and version control.
